@amitmvaghela Welcome to HP Community!

I understand that you are getting 0xC000021A blue screen and boot device not found error.

Please perform the below steps and check.

Test your hardware for issues

1. Please, shutdown the computer using the power button

2. Power it on.

2.1 As soon as you press the power-on button, immediately start hitting the Esc button (like tap-tap-tap).

This should open a HP Startup Menu which may look similar to this one

3. Choose F2 to open System Diagnostics. Follow the on-screen instructions to perform System Test >> Quick test.

This will check major hardware componets for issue (do it just in case) . Here is more info >> http://support.hp.com/us-en/document/c03467259#AbT1

If the tests pass without issues, continue. If not, please, let me know

Post back the results.

Based on this Microsoft article > https://msdn.microsoft.com/en-us/library/windows/hardware/ff560177(v=vs.85).aspx

the issue could be caused by some Windows corruption or some virus/malware.
